i. This invention relates togvcar roofs ofthe liexible'outside metal type wherein likev gage rooting sheets are loosely secured tothe car and to eachother in a manner adapted to permit 'relative movement of said roof sheets tol a limited extent so as to be able to acA- commodate themselves tothe distortions of the car body. H i

The principal object ofthe present invention is an improved seam 'construction that vwill permit a. limited sliding movement of the roof sheets transversely of theseain and vwill secure a limited pivotal or sluing move- Y ment of said sheets in all positions of their l Y i plicity of construction,v compactness and- *sliding movement. Otherobjects arersimeconomy of design, fewness of parts and they occur, A i

Thel invention consists of principally in shaping and arranging the, cooperating portions of the seam covers and the roof sheets so that the sheets are slidable crosswise to said seam coverv and are adapted to pivot thereon in any position `ot their! sliding movement. The invention Afurthe'r'consists in the parts and in the arrangements and combinations-of parts hereinafter described and claimed.A i

Fig. 6 is a plan View .the middle portions'j j ksection straddle the spaced ridge iianges 13 side plates `S and a ridge pole 9; Metalroof 'sheets and thence downwardly to form upstanding side and ridge seam iianges orhol ysheets 10 'are arranged on roof sheath-I ing 7 side byside in two rowson 'opposite sides of the` ridge, the vtwo rows of roof sheets being spacedapart at-the ridge, and

the sheets in each row being spaced apartA at their sides. 'Ther'oof sheets on opposite sides of ythe ridge are arranged in aline# vmargins ofthe sheets so as to permit a limited angular movement of thesheets betweenmiillionsy Y .f `i

The ridge Vand* side margins lof the roof sheets are turned upandare thence: ybent inwardly over the body portions oftheV low ribs 12 and 13 of substantially C-shaped section. The eaves ends of the Vroof sheets are doubled-under to'form `hooky flanges' 111l that loosely engage the .doubled-overhook aiiges 15et of angle flashing strips lfsecu'red to the eaves of they car, sucharifa'ngen'uent servingy to yloosely vretain the' sheets at the The adjacentv side seam' anges 12 ofthe sheets,together`withthe mullions 11 located therebetween, are coveredby inverted lchannel-shaped transverse orsidefseam covers or ,y

caps 16 that extend from eaves to ridgeand frestvonlsaid battens.- vThe side walls of the` Vsiders'eam covers 16 haveY inwardly and `upfwardly extending hooked flanges 17 that in f terlock with the side seamlanges 12 of the i sheets. The eaves ends of the side yseam covers 16 are looselyheld in position by exy tensions 16a that are turned downyover'the f eaves and; ends of the `mullions "and" are Athence turr'ied under the eavesV corners; of

theroof sheets and hookedv into the doubled-v back flanges ofthefe'aves flashing strips Pressed 'metalf seam ridge covers or caps- 1,8 of substantially,inverted' channel-shaped of adjacent sheets and have voutstanding base `flanges`18va that rest --on thel body portions lli) mai-mevemellt,

Vridge seamV flanges 13 of the roof sheets.

rlfhese grooves extend transversely of the spaced ridgeseamflanges from side to sidev thereofV midwayof their length and are made wider at their ends than at their middle "f preferably by bowing, their opposingy side walls outwardly from end to end of said grooves to form reversely curved or convex snrfaces 2l. Vrlfhe width of the grooves 20 midway of Vtheir length correspond to the ywidth, ofV the transverse rib 19 of the ridge seam covers, whereby said ribs have a seam, lit in said, groove midway oftheir length and arenormallv spacedztherefrom at'tlieir ends.

By the arrangement described, the ridge ends of thesheets are properly centered between the adjacent roof mullions b-y the rib and groove, connections between, the ridge seam coversjand root sheets, and said sheets are' aadbPGdv to accommodate themselves @lufoma'rically t0 the distortions of th@ Caybodyrby.sliding-towards and away. from eachL other along thetnansverse Lribsofv the ridge seam covers, and by rockingl 'npoii'v the' inf, wardly extending ribs of the ridge seam Cov-f ers. An, importantl advantage A of; thel above arrangeineiitfv is that it secures ,.afsluing or. pivotal movement of the S.heets varound. points located..z inI -theregionof'vthe middle .of-
